Description
Air insulated switchgear (AIS) series KYN28A-12 (GZS1) is armored removable AC metal- enclosed switchgear. It is suitable for three-phase AC 50Hz power system for receiving and distributing power and controlling, protecting and monitoring of the circuit in real time. The newly introduced and developed large current and high breaking switchgear can also be used as a high-voltage generator export.
